Abstract: An example camera movement control method includes: activating, by an electronic device, a camera functionally connected to the electronic device; displaying, on the basis of the activation of the camera, an image of an object outside the electronic device on a display functionally connected to the electronic device; confirming the movement of the image of the object; and correcting the image by means of an image stabilizer functionally connected to the electronic device on the basis of the movement. The correcting of the image can include: calculating an image correction angle with respect to the movement; and controlling the image stabilizer based on the image correction angle.

Abstract: An electronic device includes a camera; a motion sensor; a memory; and at least one processor. The at least one processor may be configured to acquire motion information of the electronic device from the motion sensor according to executing an image acquisition mode; determine an image stabilization scheme based on at least one part of the motion information; and perform a stabilization operation on at least one image acquired through the camera, based on the determined image stabilization scheme. The image stabilization scheme may include a first stabilization scheme for correcting shaking of the at least one image based on a first margin region; and a second stabilization scheme for correcting shaking of the at least one image based on a second margin region larger than the first margin region.
